Soil test crop response approach for chickpea in an Inceptisol
Author(s): SH Salunkhe, AD Kadlag and SA Durgude
Abstract: A field experiment “Nutrient requirement of chickpea by conjoint use of organic manures and chemical fertilizers based on targeted yield approach on Inceptisol†The data on initial soil test values for NPK, pod yield, NPK uptake and fertilizer nutrients applied were used to calculate the basic parameters viz., nutrient requirement (NR), contribution from soil (CS %), contribution from fertilizer (CF %) and per cent contribution from FYM.
The nutrients required to produce one quintal chickpea are 1.53 N, 0.26 P and 1.72 K kg q-1 respectively. The contribution of soil is 9.32, 15.95 and 6.03 per cent for N, P and K respectively. The per cent contribution of fertilizer without FYM is 55.27 percent for N, 8.10 per cent for P and 56.61 percent for K and it was increased as 60.6 percent for N, 9.8 percent for P and 64.0 percent for K in presence of FYM. The data on basic parameters viz, nutrient requirement, contribution from soil, contribution from fertilizer, soil test values, uptake of NPK nutrients and yield were used to formulate the fertilizer prescription equations for chickpea (cv. Phule Vikram) on Inceptisol.
